This example shows that the AUDIO light is
flickering "ON" and "OFF" when the ring signal is
off. The cure for this would be to turn down the
SENSITIVITY. This problem could result from
high levels of noise over the phone line. If this is the
case the noise can be heard through the SPEAKER.
Decreasing the SENSITIVITY will cure the problem
in most cases. Like the majority of the soliciting
machines on the market today, the SYSTEM will not
function on telephone lines that have EXCESSIVE
noise. If the noise is the same volume as the audio,
the noise is too severe. We have found that
sometimes the excessive noise is due to the party's
line that you are calling. To confirm this make a
short list of different prefixes in your area and try
calling them. You might find that you only
experience problems when dialing certain prefixes.
These are usually the older prefixes in the area.
Making the Adjustment
1) Obtain a small standard bladed screwdriver that
fits the SENSITIVITY trimmer.
2) Program the system to make several calls to a
known telephone number.
3) After the dialer has dialed a number carefully
watch the AUDIO light in respect to what is
heard over the SPEAKER. The light should be
on solidly when the phone is ringing, and be
completely off between rings. When the call is
answered and the called party talks, the light
should be on ONLY while they are talking. See
the diagrams in this section for more details.
Make adjustments if needed. The TRIMMER
should ONLY be turned 15 degrees at a time.
CLOCK-WISE = Increase Sensitivity
COUNTER CLOCK-WISE = Decrease
Sensitivity
The pre-calibrated position is approximately at
the 3 o'clock position.

Tape Related Problems
Faulty or worn out cassette tapes WILL cause
the system to malfunction. In order to prevent
problems you should replace all tapes before they
wear out. Worn tapes can be detected by physically
inspecting the tape surface. If the surface has
irregularities such as bubbles, non-smooth areas, or
deep lines, the tape is bad. Good tapes have a
consistent smooth surface.
Remember that the RECEIVER tape has 7
seconds on NON RECORDABLE leader at the
beginning of the tape. The tape must be ran forward
for at least 7 seconds after it is fully rewound. The
RESET R TAPE function at the beginning of both
dial sessions will automatically set the leader tape
past its leader.
